Clash of the Princes is duology consisting of (The Warrior's Way and The Warlock's Way) released as a boxed set by Puffin Books in 1986, written by Andrew Chapman and Martin Allen and illustrated by John Blanche.[1] They can be played as standard Fighting Fantasy gamebooks or combined for a two-player experience. In the two-player game, two scores (Action and Status) are kept track of on a piece of paper in order to keep both players' game experiences synchronized.

The books are set in the land of "Gundobad" on Titan, but the books do not say where or when Gundobad is on Titan, leading fans to speculate about its location. They were the first Fighting Fantasy books to drop out of print as retailers at the time were not fans of boxed sets.[2]
